Head Office and Tokyo Works1968

In 1964, the year of the Tokyo Olympics, SANYO DENKI revamped its
management team with the founder Hideo Yamamoto stepping down tobecome chairman and Hiroshi Yamamoto becoming the second president.
The goal of this personnel change was to facilitate the transition from theold to the new generation and indicated our strong determination to wager
on our future development.
Following that, we developed the San Ace thin form-factor cooling fansthat greatly boosted our position in the small-sized motor field, and small
step-angle stepping motors that won large-volume orders from IBM
Corporation of the United States for use in computers and peripheraldevices, and took great strides toward a new era with the policy of "beinga step ahead of the world's technology standards."
Tokyo Works supported our company's development through the
production of these small-sized motors.

Motoichiro Naruse Operating Ofﬁcer

SANYO DENKI Group’s 8th Mid-term Management Plan, a 5-yearplan started in April 2016, marks its final year in 2020.
“Continue to develop world-leading products in terms of quality,
performance, and reliability” is one of the main initiatives of this plan.
“Continue to develop” expresses that, rather than merely engaging
in product development, we emphasize the element of ceaselessness. To
accomplish this initiative, enriching the design environment (both people
and equipment) and securing R&D funding are essential. However,
SANYO DENKI Group places the greatest emphasis on “Working
closely with our customers and listening to their voices.”
We also strongly value working closely with and hearing the viewsof our subcontractors and business partners who provide us with raw
materials and parts. Through mutual factory tours and technology
exchanges, we strive to forge relationships that enable us to stay abreastof the latest raw materials and parts technologies, and reflect this inproduct development in a timely manner.
Furthermore, to offer world-leading products, we do not focus our
product development on sales volume. Rather, of the above-mentioned
principles of “quality, performance, and reliability,” we give our top
priority to quality. This development policy of making quality our top
priority helps distinguish our products in various markets.
In this volume of Technical Report, we will introduce the main new
products and technologies released in 2019 in “Technical Developments
in 2019.”
Cooling Systems products, Power Systems products, and Servo Systems
products all incorporate the results of manufacturing (“monozukuri” inJapanese) working closely with customers.

SANYO DENKI Technical Report No.49 May 2020

The San Ace Controller was developed in response to customers’
requests for remote fan monitoring and preventative maintenance via
the internet amid the rapid proliferation of IoT. With the fan automatic
control function, excessive increase of speed can be prevented, thus
significantly contributing to the realization of high energy efficiency andlow noise in our customers’ equipment.
Due to the frequent occurrence of typhoons, earthquakes, and othernatural disasters in recent years, there has been a growing demand for
UPSs as backup power supplies for outdoor ICT equipment, such asbase stations and remote monitoring devices for disaster management.
The SANUPS N11B-Li UPS equipped with lithium-ion batteries was
designed to meet customer needs for an outdoor UPS that has a wide
operating temperature range and require no battery replacement.
The SANMOTION K series is a new product in our lineup of DC servo
motors, which have a 60-year long history of monozukuri. This product is
an ideal example of our “Continue to develop” principle. In recent years,
our products have often been used in precision measurement devices andmedical equipment. To improve measurement accuracy, such applications
require servo motors to have low speed fluctuation and temperature rise.
Furthermore, as such devices are installed in quiet environments close topeople, servo motors with low noise are essential. This product satisfies
these needs of our customers.
A close look at the market environment reveals turbulent andaccelerating change best represented by keywords such as AI, IoT, 5G,
labor-saving, and disaster management. These changes are occurring
on a global scale. The SANYO DENKI Group will ceaselessly pursue
our principle of “monozukuri working with our customers” so we may
skillfully handle these changes and contribute to our customers’ value
creation.

optimal design for excellent airflow efficiency. Moreover,
we increased the frame strength over the current models tosuppress the increase in vibration caused by higher speeds.

In recent years, equipment has been becoming smaller
and thinner, and the cooling fans used inside it are also
required to be smaller and thinner.
There is a particularly strong demand for higher cooling
performance in compact, thin profile devices like graphics
cards embedded in equipment that is becoming increasingly
high performance.
Centrifugal fans are suitable for these applications, andthere is a need for smaller and thinner centrifugal fans withhigher cooling performance.
To meet this demand, we developed the ø70 × 20 mm
San Ace C70 9TD type Centrifugal Fan (hereinafter “newmodel”) that is compact and thin profile in a size which is a

lower SPL and power consumption.

The key points of development are explained below.

4.1 Compact and Thin Profile
To make the fan smaller and thinner, the motor needed tobe made smaller. However, motor heat generation and motor
torque issues arose. We solved these issues and achieved athickness of 20 mm by taking the following measures.
(1) S olution for motor heat generation
We successfully suppressed the motor’s temperaturerise due to heat generation by using a die castaluminum frame with excellent heat dissipation andestablishing a self-cooling structure with vents on

T h is a r ticle i ntroduced some of the featu res a nd
performance of the ø70 × 20 mm Centrifugal Fan San Ace
C70 9TD type.
With a higher-efficiency motor and optimized structure,
the new model realized high cooling performance despite
the compact and thin profile.
In the future, it is expected that equipment in the market
will become smaller and thinner. Accordingly, there will belimited component installation space inside equipment, andthe resulting higher density will make it more difficult tosecure an airflow path.
The new model is the most compact of our Centrifugal
Fans, and with its high airflow and static pressure, we
believe it will greatly contribute to solving our customers’issues.
We will continue to stay ahead of the diversifying market
and develop products that create value for our customers.

to significantly improve energy
ef fic ienc y and p ro du c ti v i t y. In
addition to the ongoing advance of
5G communication and the predictedfurther growth in popularity of AI
technology, countries around theworld are advancing their respective
initiatives,(1) and it is expected that
this will bring innovative change
to the manufacturing and logistics
industries in the 2030s.
Meanwhile, 2019 was also a year
in which uneasiness toward climatechange intensified considerably.
In the past five years, the highest
average global temperatures everrecorded (2) have been reached. In
addition, the sea rise forecast for
the year 2100 increased significantly
over previous forecasts.(3) In Japan,

a number of large-scale typhoons

warming, and networking products.
Many of our customers have highexpectations for such products asessential equipment to maintainfac tor y pro duc tion and critic alinfrastructure. In 2019, the Power
Systems Division released thefollowing new products.
Starting with UPSs, we developed
the SANUPS A11M highly-reliablep arallel redund ant UP S, which
can be used all over the world. In

addition, we added new models to
our SANUPS N11B-Li and SANUPS
A11K-Li lineups of UPSs equippedwith lithium-ion batteries, which wehave been aggressively expanding
in recent years.
In terms of renewable energyrelated products, we enriched thelineup of our SANUPS W73A power
conditioner for wind power andhydro power generation systems,
adding a grid-connected isolated
type that can be used during power
outages.
For net working products, wedeveloped the SANUPS LAN Interface

3. Features
3.1 Maintainability and backup time after
aging deterioration

Battery module(LIB)

Inverter module

W hile SA NUPS A 11K series U PSs with lead-acidbatteries require battery replacement approximately every
five years, the new models, thanks to the LIB, can operate
for roughly ten years without battery replacement. This
maintenance-free operability reduces maintenance workand battery replacement costs.
Furthermore, an LIB has less capacity reduction due toaging deterioration compared to a lead-acid battery. Thismeans that, when we compare the backup time at the endof battery life, the backup time for the lead-acid battery isapproximately half the initial value. By contrast, the backup
time for LIBs only drops 10%, meaning that the change
in backup time due to aging deterioration for the latter isextremely minimal.

(1) New model SANUPS A11K-Li (1 kVA)

Battery module(Lead-acid battery)Inverter module

3.2 Operating temperature range
The operating temperature range of the SANUPS A11K
series equipped with lead-acid batteries is -10˚C to +55˚C(charging stops at +40˚C to protect the battery). By contrast,
the operating temperature range of the new models is -20˚C
to +55˚C, making them suitable for both extremely cold andextremely hot environments.

3.3 Equipment size and mass
Figure 2 (1) and (2) show the interiors of SANUPS A11KLi (1 kVA) and SANUPS A11K (1 kVA), respectively. Table
2 shows a comparison of the volume and mass for the new(2) Current model SANUPS A11K (1 kVA)

Fig. 2 Interior of new model and current model

short backup time models and the current models.
Figure 2 (1) shows that, for the new short backup timemodels, we were able to fit the LIB in the space occupiedby the lead-acid battery without changing the size or shapeof the current housing. LIBs are lighter than lead-acidbatteries, therefore, as demonstrated in Table 2, the new
short backup time models are up to 44.8% lighter thancurrent models of equivalent size.
Table 3 shows a comparison of the volume and mass forthe new intermediate backup time models and the current
models. As Table 3 shows, the new intermediate backup
time models are smaller and lighter than the current models.
On the current models, an external battery unit is necessary
to provide 19 minutes of backup time. Therefore, volume,
mass, and space occupied on a rack are all greater. For the

1. Introduction
IoT has been incorporated in production lines at an everincreasing pace, and it has become common practice tomonitor the operating status of industrial equipment remotely.
In such an environment, demand is increasing for a

Modbus RTU protocol, which uses serial communication.
The new models are divided into two groups: one that
supports the Modbus TCP protocol, and another that supports
both Modbus TCP and Modbus RTU protocols.
Figure 1 shows PRLANIF021A, which only supports the
Modbus TCP protocol.

single monitoring system that can batch monitor industrial
equipment and uninterruptible power supplies (UPS) used forbacking up this equipment.
We developed the SA N UPS L A N Interfa ce C ard(hereinafter, LAN Interface Card) as a UPS optional product.
It is used for monitoring UPSs remotely, and for shutting down
computers in data centers and server rooms automaticallyduring power failures. However, with the increased popularityof virtual servers, there is growing demand to use LAN
Interface Cards in equipment with comparatively complicatedshutdown procedures.
To respond to the above demands, we have added or

This article provides an overview of the newly developed
LAN Interface Card (new model) and introduces its features.

2. Product Overview
The new models maintain all functions of our current
product and feature an additional Modbus communication
function.
There are two forms of Modbus communication: the Modbus
TCP protocol, which communicates over networks, and theFig. 2 PRLANIF023A

When installing a UPS in an environment with a PLC ora monitoring control system such as a supervisory control
and data acquisition (SCADA) operating as a Modbus
master, the LAN Interface Card is set to Modbus slavecommunication. The UPS can be remotely managed from
Modbus masters, enabling users to check UPS operating
status and control the UPS (battery test, UPS stop, UPS
start).

3.1.3 Modbus master function
When connected to a Modbus slave unit such as an I/O
unit or measuring instrument, the new models can monitor
status and measurement data of up to 16 points.
When importing status data, the user can set the UPS totreat a situation as abnormal when the signal status changes
from off to on, or vice-versa.
When acquiring measurement data from Modbus devices,
measurement values may include decimal numbers or
be several digits long, depending on the device. The newmodels can be set to import measurement value data from avariety of devices. Moreover, a threshold can be set for themeasurement values being imported. If readings deviate
from the threshold value, an email notification is sent toa preset email address and the event is recorded in theFig. 7 Example screen

Figure 6 is an example of a screen for registering a
Modbus slave unit to acquire measurement values.

3.2 Enhanced shutdown functions
With the WScript function, even our current LAN
Interface Cards models can safely shut down computers thatare backed up by UPSs in the event of a power failure.
When a server needs to shut down in a power outage,
with server shutdown commands registered to the LAN
Interface Card, this function uses the SSH/Telnet protocol
to remotely operate the server, log in, and then use theregistered commands to shut down the server.
In conventional server environments, servers, data storage
devices, network devices, and other infrastructure all used
dedicated hardware. But in recent years, there has been
an increasing use of virtualized servers that integrate andoperate multiple OSs within a server and hyper-converged
infrastructure (HCI) that virtualizes infrastructure

must be performed in a certain order.
With current models, there was a limit to the registration
capacity for WScript commands, and sometimes it was notpossible to set all of the procedures necessary to shut down
virtualization platforms.
On the new models, the command registration capacity
was increased from 598 to 10,238 bytes: sufficient space forcomplex virtualization platform shutdown procedures.

20 mm wide model. We increased
thrust by optimizing the magnetic
circuit and the combination of thenumber of coils and the numberof poles while achieving a 14%
increase in the motor’s maximum
acceleration over our current
model by reducing the weight ofmoving elements. Maintainability
has also been improved thanks
to a self-lubricating linear guide.
With improved acceleration andmaintainability, this product canhelp improve the p er for manceand reliability of semiconductor
manufacturing equipment and othermachinery.
Regarding AC servo amplifiers,

SANYO DENKI Technical Report No.49 May 2020

we have added models with a builtin positioning function to the lineup
of our SANMOTION R 3E Modelseries. T he built- in positioning
function provides customers ahigh degree of freedom, allowing
positioning control for up to 254
points, continuous operation, andsimple program operation. This
product allows customers to build
systems easily without using a
dedicated positioning controller,
contributing to downsizing and wiresaving of customers’ equipment.
For interfaces with host controllers
such as PLCs, we have prepared thefollowing two types: a parallel typewith contact inputs and outputs,
and a serial communication type
(RS - 485, Modbus RTU) to allow
customers to choose the one best
suited to their systems.

1. Introduction
Most workpiece conveyance and machining operations ofsemiconductor manufacturing equipment, mounters, andmachine tools move linearly. As such, linear motors that arecapable of linear motion without using a ball screw or otherlinear motion conversion mechanism are widely used in theseand various assembly equipment.

the application and axis motion direction.(1)3. Specifications of the New Model

Semiconductor manufacturing, inspection, and various

has multiple axes to perform (vertical) pick-and-place
operations. Compact cylinder linear servo motors canhelp downsize this equipment, simplify mechanisms, andimprove productivity. To respond to greater market needs,
however, the current 12 mm wide model needed a higher
thrust and longer stroke. The following are the specification

While servo gain and other parameter files are notcompatible, we have prepared a tool that automaticallyconverts parameter files prepared for the current models sothey can be used on the new models.

4.2 Standardized design
To support the rich SANMOTION R 3E Model lineup,
we focused on standardizing design, thereby shortening thedevelopment period.
(1) Standardized output circuit
T he current models have different output circuits
for different controller input specifications (sinking or
sourcing). The new models, however, have standardized
output circuits that support both.
(2) Standardized components
As far as possible, components have been standardized
with those of analog/pulse train and EtherCAT models(such as resin cases and die castings) to improve structuraldesign efficiency.
(3) Integrated software
We have shortened the software development period byinnovating software configuration and module design, andintegrating the software for parallel and serial types.
(4) Reduced number of product models
By standardizing output circuits and making Safe TorqueFig. 9 Point data setting/editing screen
